Specification of Letters Patent.

Patented Sept. 19, 1911.

Original application filed June 21, 1908, Serial No.- 440399. Dividedand. this application filed October 12, 1910. Serial No. 586,749.

lb all whom it may concern: Be it known that I, Russnm. HUFr a citizen of the United States, and resi ent of Detroit, Wayne county, State of Michigan,

-have invented certain new and useful Improvements in Motor-Vehicles, of which the following is a specification.

This a plication is a divison of my application, e'rial No. 440,699, filed June 27, 1908.

This invention relates to motor vehicles and particularly to the fan driving mechanism of a hydrocarbon motor used in such vehicles.

It has special reference to the means for operating the adjustable fan which is ordinarily used to circulate air through the radiator for cooling purposes.

It has been customary heretofore'to drive the fan from a pulley attached to the projecting 0nd of the motor crank shaft. This has been found objectionable because of oil leaking around the packing of the projecting end of the crank shaft, which oil is picked up by the rapidly rotating fan pulley and thrown by centrifugal force in all directions. The present invention is intended to overcome this defect and secure other advantages hereinafter described. To this end I arrange the end of the crank shaft wholly within the gear case which is transversely arranged at the front end of the crank case and extend the clutch of the starting crank through a packed bearing in the front wall of the gear case to a position in proximity to a clutch on the front end of the crank shaft. As the starting crank is rotatcd only when it is manipulated for the purpose of starting the motor, it is an easy matter to maintain a tight joint around its shaft. Since by this arrangement. there is no projecting end of the crank shaft from which to drive thefan, I use one of the auxiliary shafts for the purpose, and in the present instance 1 connect the fan to a pulley u!) the llltlgllelt. sha t. 'In order to secure relative adjustment between the driving and driven shafts r I have devised bracket iug it.

Other features of my invention and their operating the fan, a very simple ml uStaIJdo fan and improved means for mount advantages will be apparent from the following description.

In the accompanying drawings, Figure 1 is a front elevation of a motor for a motor vehicle, embod ing my invention; Fig. 2 is a view part y in vertical section of the fan and its adjustable bracket; and Fig. 3

1s a cross section on the line 33 of Fig. 1.

In the drawings, 1 represents one of the cylinders of a hydrocarbon motor which is provided with the inlet and exhaust chambers '2, 3. The crank case 4 has preferably at its front end the laterally extending hollow arms 5, the ends of which are adapted to rest upon the side bars of the motor vehicle, as is well understood. These hollow arms form a gear case 6 in which are mounted a train of gears for shafts, water pump and magneto for properly operating the motor. The crank shaft 7 extends through from the crank case into the gear case 6 and there terminates, carrying upon its end the clutch teeth 8 with which the clutch teeth o f the starting shaft 10 cooperate in the usual manner. The startingshaftis provided with the usual crank arm 11 and handle 12 for manually operating it to start the motor.

The front end of the gear 6 is rovided with a removable cover 13 to whic l is secured a sleeve 16 in which the starting shaft 10 is mounted. For a further descri tion of this starting shaft referencema e had to the above mentioned parent appiicaion.

0n the end of the crank shaft 7 is secured a driving gear 24 which meshes with the cam shaft cars 25 and 26, which latter gears drive t is gears 27, 28 on the pump and magneto shafts respectively. The gears 25, 26, are bolted to flanges 32, 33, on the respective cam shafts 34, 35, in the usual manner, and the gear 27 is suitably attached to the pump shaft 36. The gear 23 is attached to magneto shaft 37 which is mounted in spaced bearings '38 in the crank case arm and this shaft is oiled by the spray from the crank ruse which passes up through a channel 39 leading from the interior of the crank case [0 the central part of the shaft. On the rear end of the shaft 37 is mounted one of the members 40 of a universal coupling by driving the cam.

the

which it is eminccted hi'ith the armature shaft 4 1 of the magneto 42. The member 40 has an annular flange 43 formed integral therei'vilh, and totllisilange is bolted the web of a pulley ll, which pulley extends forwardly from said shaft. t

The L\ullcy it is arranged in a vertical plane with a pulley lii ivhich is secured to 'the'hub of a fan 4h so that the fan may be driven by a belt 47 passing over these pulleys.

The fan and its pulley are mounted upon a bracket on the front side of the forward motor cylinden and this bracket is adjustably secured to a bracket carried by the cover of-t he water jacket of the cylinder. Luis will 'bcscen l-iy refi'tuice'tn F ig. 2, the hub (57 of the fan'surrmmils the spindle 48 and is mounted on ball bearings thereon. This spindle 4.8" projects forwardly from the; bracket 49, being -rigid therewith and formed in any siiitahle way. As shown, it is screwed into a suitable boss on'the bra "hot. The bracket 15 is formed of a central verti- 'eal portion 50 Which carries the spindle 48,

an u nvardly extending screw-threaded portion or arni' (i1; and 'tivo downwardly extending sepm-na'ii-arms 52 which are bifureated utth'cir loWer'e'nds forming slots 130 parallel with the and 51 The arms 52 are adjustablysecuredto theend wall of the cyli'nder by bolts '53 fastened through the "slots. The arm fil passes through an open ing 54 formed ina forward extension 54 of a bracket carried by the water jacket cover 56, and is adjustably secured to said latter bracket by the two nuts 57 arran ed on opposite sides of the extension 54'. By adjusting thcsenuts the bracket may be raised or lowered and may be held firmly "in adjusted position by the nuts 57" and the bolts 53, thus permitting tension adjust ment of the belt 17.

The bracket 55 carried by the water jacket cover 56 may be integral with the cover or may be sccurrd thereto in any suitable Way. This lJlilUlilii has a suitably inclined ledge 58 upon which is mounted a support 59 for the high tension ignition wires of the motor, this support being preferably composed of fiber block with suitable openings (30 therein for the passage of the ignition wires 61. which are adapted to be connected with the magneto.

Having thus described my invention, what I claim is:

1. In -a device of the class described, the combination .with a crank case having a laterally extending arm, of a magneto shaft mounted in hearings in said arm a member of a universal coupling on the end of said shaft, a flange on said member, and a pulley secured to said flange.

2. In a device of the class described the combination with. the crank ease having a laterally extending arm, of a magneto shafi mounted in hearings on said ari'n, an armature shaft for the magneto in line with said shaft, a universal coupling joining the ends of said shafts, a flange on the member of the universal coupling on the magneto shaft, and a pulley having its web bolted to said flange.

In testimony whereof I ailix my signature in presence of two Witnesses.
